Pin 3 (CTRL)
This pin provides an Off function which puts the converter into a low power mode. When the pin is ‘high’ the
converter is OFF and when the pin is high ‘Z’ the converter is ON. There is no allowed low state for this pin. Voltage
to be applied via a limiting resistor with a recommended value of 1K for RSO-05xx; 3.3K for RSO-12xx; RSO-24xx
and 10K for RSO-48xx.
